SRP4020, SRP7030F power inductors

From Bourns Inc. come two new power inductors that feature advanced flat wire technology for lower DC resistance and higher current ratings in an ultrasmall package.

Bourns' power inductor design uses a flat wire within a molded magnetically shielded housing that enables lower DC resistance and slightly higher current ratings compared to traditionally-used round wire. Designated the SRP4020 and SRP7030F, the new inductors are suited for use in DC/DC converters for mobile electronic devices and computers, as well as data storage and voltage regulator modules. Other applications that can benefit from Bourns' advanced power inductor design include servers, portable gaming devices, navigation systems, automotive electronics, medical equipment and more.

Bourns' SRP4020 features a very compact footprint of 4.8mm x 4mm in a 2mm height. The device has an inductance range of 0.22?H to 2.2?H, with a heat rating current up to 10A and a saturation current up to 15A. Model SRP7030F also offers a compact footprint of 7.6mm x 6.5mm in a 3.2mm height. The inductance range is 0.1?H to 10?H, with a heat rating current up to 32A and a saturation current up to 60A.

Pricing for the power inductors is $0.68 each in 1,000 units.
